Default Java Persistence Data Source for Embedded GlassFish Server

The jdbc/__default Java DB database is preconfigured with Embedded GlassFish Server. It is
used when an application is deployed in Embedded GlassFish Server that uses Java
Persistence but doesn't specify a data source. Embedded GlassFish Server uses the embedded Java
DB database created in a temporary domain that is destroyed when Embedded GlassFish
Server is stopped.

By default, weaving is enabled when the GlassFish Server Embedded Server API is
used. To disable weaving, set the org.glassfish.persistence.embedded.weaving.enabled property to false.
